Uburyo Mpuzamahanga bwo Kugenzura Igihombo Gikomeye n'Ikiza cyose
Sisitemu yo gufunga imiyoboro ya Foam Wedge Lost Circulation System, ishobora kuziba imvune zigera kuri mikoroni 40.000, yashyizwe mu bikorwa na Halliburton mu bikorwa byayo mu bihugu bibiri byo mu Burasirazuba bwo Hagati (Oman na UAE).
Imbogamizi mu miterere karemano y'imvune/imvune
Gukemura ikibazo gikomeye cy’ibihombo bikomeye mu miterere y’uturemangingo twavunitse cyangwa twacitsemo ibice bisanzwe byari bigoye, cyane cyane mu Burasirazuba bwo Hagati. Ibikoresho bisanzwe bitakaza inzira z’amaraso (LCM) bikunze kunanirwa bitewe n’uko ingano y’aho imvune ihagarara idasobanutse neza. Ariko, sisitemu ya Halliburton's Foam Wedge, ihuza High Fluid Loss Squeeze (HFLS) na Reticulated Foam LCM (RFLCM), byagaragaye ko bikora neza, bishyigikiwe n’intsinzi yapimwe mu murima.
Igishushanyo n'isuzuma ry'ubuvuzi bwa LCM byashingiwe ku bipimo bya laboratwari byatsinze, bigaragaza ko hafunzwe imvune zigera kuri mikoroni 40.000.
HFLS na RFLCM Dual Technology: Ibisubizo bya Laboratwari n'ibyo mu Buhinde mu bihugu bibiri byo mu Burasirazuba bwo Hagati (Omani na UAE)
Ibi bisobanuro birambuye birimo imiterere y’imiterere y’aho amazi aherereye, ingano y’aho amazi aherereye, ingano n’ubwinshi bw’icyondo cya LCM, ndetse n’uburyo bwo kugitera no kugipompa bwakoreshejwe. Intsinzi yo gukoresha yagaragajwe n’igipimo cy’igihombo cyabayeho mbere na nyuma yo kugitunganya mu gihe cy’aho amazi aherereye adahinduka ndetse n’igihe ahora acukurwa, bigaragaza igihe cyo gucukura cyazigamwe.
Muri Omani, intego yahuye n'igihombo cya buri mezi kigera kuri 125 ku isaha (bbl/hr) n'igihombo cya buri mezi kigera kuri 280 bbl/hr (galoni 550 ku munota, gpm) kigera kuri "igihombo cyose." Ihinduka ryaranzwe no gupfundika kw'amazi mu buryo bwa vugular. Intego y'umukiriya kwari ugutanga umuti mwiza wa LCM wo gukemura vuba igihombo nyuma yo kugera ku burebure bwose (TD) no gukora ibikorwa byo gusarura ibiti nta gukenera imashini zifunga sima, bityo bikagabanya igihe cyo gucukura. Uburyo bwo gusukura HFLS na RFLCM byavanzwe mu mazi, binyuzwa mu gice gizunguruka, kandi bigashyirwa mu nzira yo gusukura amazi mu buryo bwa circulating hamwe n'umuvuduko wiyongera buhoro buhoro. Nyuma yo gusukura, igihombo cya buri mezi kidahindagurika n'igikomeye cyagabanutse kigera kuri zeru, bituma ibikorwa bikomeza mu mutekano.
Muri UAE, intego yakoresheje neza amazi yo gucukura atari amazi. Mu gihe cy’ihindagurika ry’ikirere, igihombo cyari hagati ya 85 na 200 bbl/hr, mu gihe mu gihe cy’ihindagurika ry’ikirere (igipimo cy’amazi cya 990–1250 gpm), igihombo cyari 150 bbl/hr. Iremwa ryaranzwe no kuvunika kwabayeho mu buryo busanzwe. Ibice bya HFLS na RFLCM byavanzwe mu mavuta y’ibanze, binyuzwa mu gice cy’amazi gitembera, hanyuma bikorerwa inzira yo gukamura amazi buhoro buhoro hamwe n’umuvuduko wiyongera buhoro buhoro. Nyuma yo gukamura amazi, igipimo cy’igihombo cya static cyagabanutse kigera kuri 2–15 bbl/hr, kandi igipimo cy’igihombo cya dynamic cyagabanutse kigera kuri 25 bbl/hr (kigabanuka kigera kuri 5 bbl/hr mu gihe cyo gucukura), bituma ibikorwa bikomeza.
Mu bizamini bya tekiniki byo gusuzuma, ubushobozi bwo gufunga imvune/vug zakorewe muri laboratwari hamwe n’imyenge igera kuri mikoroni 40.000 byatanze icyizere cy’uko LCM ishobora guhangana n’ingano zitazwi z’imvune/vug. Gukoresha neza ubutaka byakemuye igihombo gikomeye kugeza ku gihombo cyose, byemeza uburyo bwa HFLS/RFLCM bwo gukora ibintu bibiri. Inyungu ikomeye y’ikoranabuhanga rya LCM ryateye imbere ni ukugabanya ikiguzi cyo kubaka amariba binyuze mu kugabanya igihe cyo gucukura gifitanye isano no gucunga igihombo gikomeye kugeza ku gihombo cyose.
Mu rwego rwo gushyira mu bikorwa sisitemu yo kuzenguruka kw'amaraso yatakaye yavuzwe haruguru, isosiyete yacu yateguye ibicuruzwa bibiri ku giti cyayo: umusemburo wa High Fluid Loss Squeeze (HFLS) FC-FLS n'umusemburo wa Reticulated Foam LCM (RFLCM) FC-LCM, byombi bigira imikorere ingana na sisitemu ya Halliburton ya Foam Wedge Lost Circulation System.
